Setting the default root password: Some Live Linux distributions are created without a root password by default (the root account is inactive). This is particularly true with Debian based distributions like Ubuntu. Setting a root password enables us to access some essential tools such as the synaptic installer. In most cases, having no root password is fine when your running from a Live CD and don't need to do administration tasks, make changes or install additional packages. But for those of us who do want to make administrative changes and save them back to a USB device or local storage device on for example a properly created "casper-rw" partition. Setting the root password might then be necessary.
How to set the default root password:
This process is known to work on most Debian based LIVE distributions like Ubuntu or Pendrivelinux releases previous to Pendrivelinux 2008. Other distributions may vary.
Open up a terminal and type sudo passwd root
Follow the onscreen instructions to set and confirm your new password

请问这个驱动怎么安装linux-fbdev-kernel-bin_2.6.00.02a.tgz？
各位大大：小弟最近在学习Linux，有一问题请教：我在网上下了一个主板的驱动文件名如下：linux-fbdev-kernel-bin_2.6.00.02a.tgz。从字面上看是一个需要编译的压缩文件。问题如下：1 如何在命令行下面从u盘里把这个文件copy到硬盘上？
2 把这个文件copy到哪个目录下面？
3 编译好了以后直接make install就能安装完成了吗？请解答一下，我最近在网上也搜索了一些资料，但是是总有点出入，希望能得到指点！谢谢！

Re: 请问这个驱动怎么安装linux-fbdev-kernel-bin_2.6.00.02a.tgz？
如果是桌面版5.0，U盘直接插上，然后拷入用户主目录下，然后双击桌面上的终端，执行tar zxvf linux-fbdev-kernel-bin_2.6.00.02a.tgz，然后进解压得到的目录里面去看说明文件。

Re: 请问这个驱动怎么安装linux-fbdev-kernel-bin_2.6.00.02a.tgz？
再问几个问题：1 我安装红旗5.0的时候没有设置用户，直接用的root，现在想添加一个用户，但是在桌面上和菜单里都找过了，好象没有类似于“用户帐户”的程序。是不是只能在命令行模式下面输入命令来添加用户？2 我在图形界面模式下把Linux-FBDev-kernel-bin-2.6.00.02a.tgz粘贴到/usr/scr/linux-2.6.9-5.34DT/ 中，然后解包生成了这个文件夹，下面有viafb.ko, viafb-install,viafb.modes,我不知道这几个文件应该怎么用？3 我看了readme.txt了，里面说"make sure you have the kernel sources installed in /usr/src/.
copy viafb to any directory"这段话里说的"viafb"是我问题2里面的哪个文件啊？copy到任意目录都可以？4 我登陆终端之后系统提示Localhost#，怎么进入到/usr/scr目录下面啊？我打了cd /usr/scr 为什么系统报错啊？

Re: 请问这个驱动怎么安装linux-fbdev-kernel-bin_2.6.00.02a.tgz？
‘用户设置’在在‘控制面板’里有！第四个问题是cd后面要加空格键，不要用dos的习惯来输。linux的命令后面都是要加空格的。

Re: 请问这个驱动怎么安装linux-fbdev-kernel-bin_2.6.00.02a.tgz？
那个viafb-install可能是个脚本文件，进入相应目录执行sh viafb-install试试看。copy viafb to any directory.拷贝viafb到任意目录。这个viafb是指你解压得到的文件夹。打了cd /usr/scr 为什么系统报错啊？因为只有/usr/src没有/usr/scr，所以系统报错。
